Bank of England policymakers are expected to pump another £50bn of funds into the economy next month to boost growth, despite the central bank's decision on Thursday to leave base rates untouched at 0.5% and the quantitative easing (QE) total at £375bn.

Analysts said the bank was likely to take its programme of QE to a new high of £425bn at its November meeting following a series of indicators that showed the economy is continuing to struggle.

Halifax reported a fall in house prices in September while a big boost to car sales last month appeared to follow heavy discounting and cheap finance deals that enticed customers to part with their cash.

Reports on the property market and car sales follow industry surveys earlier in the week that showed a modest bounce back after steep falls in output in the first half of the year.

The construction and manufacturing industries contracted last month and the services industry grew more slowly as fears that the Olympics would provide only a short-term boost were confirmed.

Threadneedle Street had been expected to maintain its current position, with all eyes on November for a further monetary stimulus.

The Bank's rate-setting monetary policy committee will examine the latest industry surveys and how the market for business loans and mortgages has reacted to its £80bn Funding for Lending scheme, before making a decision to expand QE.

Quantitative easing involves the bank buying government bonds from a range of financial institutions in the hope they use the money to lend to businesses and households.

Most economists expect another dose of stimulus ahead of the Christmas break, although the decision may not be unanimous.

"Some members – Spencer Dale, Ben Broadbent and Martin Weale, in our view – are closer to our hawkish view on inflation, and we think their lack of enthusiasm for doing more is likely to be clear again," said Nomura economist Philip Rush.

"However, we still doubt they will 'win the debate' and block the committee from announcing more QE in November," he said.

Chief executive of car lobby SMMT, Paul Everitt, said car sales rose by 8.2% in September, nearly twice the annual rate seen so far this year.

He said a degree of confidence had returned to car buyers, though analysts argued much of the increase could be attributed to aggressive discounting and appealing finance deals.

"Although the economic outlook remains challenging, we are starting to see a tentative return of consumer confidence," said Everitt.

Mortgage lender Halifax said house prices fell for a third month and will probably remain little changed into 2013 amid a "weak" economy.

Anna Leach, head of economic analysis at the CBI business lobby group, said the MPC was expected to delay a decision until the current round of QE was completed.

"Looking ahead to November's meeting, we think that the committee is likely to favour further asset purchases. While there have been a few positive signs in recent data, underlying conditions remain relatively flat.

"Meanwhile, uncertainty around the international backdrop is likely to build further through the autumn, keeping confidence in check."

The Bank of England printed £200bn of funds to buy bonds in the wake of the Lehmans crash and has added almost the same amount again in the past two years to stop the economy falling back into another deep recession.
